Electro-Voice RE3-ACC-OL3 Omnidirectional Lavalier Microphone with TA4F

The OL3 is a robust, multi-purpose lavalier microphone. It is ideal for presentation, public speaking, and on-camera applications where its open and natural sonic characteristics deliver accurate and natural voice reproduction. The low-profile design makes it easy to physically manage, and eliminates unsightly presence other larger sized lavaliers present. The omni-directional polar pattern has no proximity effect, and is ideal for delivering an open and natural sound, even when the user is turning their head sideto-side. The small clothing clip attaches the microphone securely to clothing items or surfaces. The included foam windscreen is effective in reducing wind noise. The 4-pin mini plug is compatible with all current Electro-Voice bodypack transmitters, as well as many other brands who use the 4-pin mini connector convention.
